Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611170, here are decompositions:

19 + 8611151 = 8611170
23 + 8611147 = 8611170
31 + 8611139 = 8611170
37 + 8611133 = 8611170
53 + 8611117 = 8611170
107 + 8611063 = 8611170
137 + 8611033 = 8611170
167 + 8611003 = 8611170

Showing the first eight; more decompositions exist.
